27.1 Register Addresses (Address Order)
The data-bus width column indicates the number of bits. The access-state column shows the
number of states of the selected basic clock that is required for access to the register.
Note: Do not attempt to access undefined or reserved addresses. Correct operation of the access
itself or later operations is not guaranteed when such an address is accessed.
